A 35-year-old woman was admitted to our hospital with the following complaints, headache, sweating, anxiety, dizziness, nausea, vomiting and severe hypertension. The technical images (abdominal CT, scintigraphic octreotide scan and renal arteriography) revealed the presence of a left adrenal pheochromocytoma and stenosis of the renal artery. Ten days following adrenalectomy, watery diarrhea appeared. The long-acting somatostatin analogue octreotide (LAR, 30 mg/month, i.m.), was started, and after 2 weeks diarrhea decreased and gradually disappeared. In conclusion, we were confronted with an unusual case of pheochromocytoma associated with renal artery stenosis and the appearance of watery diarrhea some days after surgical treatment. Treatment with octreotide brought about the remission of diarrhea in this patient.

To evaluate the possible role of the kidney in the enhanced metabolic clearance rate (MCR) of GH in obesity, we studied the kinetics of GH and renal fractional extraction of GH (RFEGH) in 12 male hypertensive patients over a wide range of body weights (71.7-129 kg) while undergoing contrast angiography on suspicion of renal artery stenosis. A continuous infusion of recombinant human GH was administered during a continuous infusion of somatostatin to suppress endogenous GH secretion. After 2 h of GH infusion, when plasma GH had reached a steady state at concentrations that were still in the physiological range, blood was sampled from the left and right renal arteries and veins for determination of GH levels. Subsequently, the GH infusion was stopped, and GH kinetics were investigated with noncompartmental analysis. In none of the patients was hemodynamically significant renal artery stenosis present. Whole body MCR of GH averaged 375 +/- 142 ml/min. Average GH levels were significantly higher in arterial plasma than in simultaneously sampled renal venous plasma (P < 0.001). RFEGH was 8.6 +/- 6.8%. The MCRs of both GH and RFEGH correlated significantly with body weight, body fat mass, and endogenous creatinine clearance. Renal uptake of GH per 100 g kidney tissue correlated inversely with MCR. These results suggest that RFEGH rises with increasing adiposity, but per unit of renal mass, the capacity of the kidney to remove GH from the circulation falls at high MCR values.
